What is an excavator telescopic arm
A telescopic arm for an excavator consists of a sturdy main structure, an extendable sliding section, a steel cable system, and a hydraulic telescoping cylinder. By modifying the sliding sections, the arm can achieve optimal reach and excavation depth. When used with a bucket, it enhances efficiency in deep digging operations, including soil, sand, and coal handling.
The two-section boom is built with LG700 steel for superior toughness, while Q355B components contribute to a lightweight yet reinforced design.
22-ton bucket cylinder for powerful excavation
Enlarged spring plates in the reel system for durability
Multi-layered bearing system for reinforced support
High-strength LG700 steel box frame for stability
Pivot structure reinforced for improved load endurance
What are the advantages of our telescopic arm?
High-Strength Materials – Uses specially reinforced steel to optimize strength while keeping weight low.
Greater Digging Efficiency – Achieves an extra 20 cm reach beyond standard telescopic arms.
Optimized Cylinder Support – A double-slider design minimizes vibrations, extending lifespan.
Upgraded Hose Durability – A dual-layer protective cover reduces wear from movement.
Simplified Maintenance Design – The exposed bucket cylinder allows for quick and easy servicing.

FAQ
Q: Are you a manufacturer?
A: Zhonghe machinery offered a wide range of attachment parts for excavators and dozers. Such as long reach arm, demolition arm, telescopic arm, standard bucket, rock bucket, cleaning bucket, tilting bucket, etc. We know that the perfect combination of high-quality cast steel products and a moderate price is the key to the success.
Q: Is the length of the telescopic arm the total length or the digging depth?
A: The length of a two-stage telescopic arm refers to the digging depth. For example, a 14-meter telescopic arm means that the maximum digging depth is 14 meters, so it is called a 14-meter telescopic arm. The actual arm length is not only 14 meters.
Q: What material is the telescopic arm made of?
A: The arm tube of the telescopic arm is made of a690 or HG785
material, and the material of other parts is a355B material.
Q: What are your terms of payment?
A: We prefer T/T (50/50) through Ali Credit Insurance as a trial
order.
Q: Are you always delivered on time?
A: We can't promise about the sea freight but what we can do is
shorten our lead time while keeping the same quality level. So
there will not be any problem even if the sea freight is delayed
for a couple of days
